"By the grace of Allah, you are gentle towards the people; if you had been stern and harsh-hearted, they would have dispersed from round about you." The noble Qur'an, A'al-Umran(3):159
The following is a Hadith from the books of Bukhari and Muslim:
Hadrat Anas ibn Malik (may Allah be pleased with him) said: While we were in the mosque with Allah's Messenger (may Allah's blessings and peace be upon him) a desert Arab came and began to pass water in the mosque. The companions of Allah's Messenger said, "Stop! Stop!" but Allah's Messenger (may Allah's blessings and peace be upon him) said, "Don't interrupt him; leave him alone." They left him alone, and when he had finished, Allah's Messenger (may Allah's blessings and peace be upon him) called him and said to him, "These mosques are not suitable places for urine and filth, but are only for remembrance of Allah, prayer and recitation of the Qur'an," or however Allah's Messenger expressed it.* Hadrat Ibne Malik (may Allah be pleased with him) said that he then gave orders to one of the people who brought a bucket and poured water over it. (Bukhari and Muslim)

THE SIMILITUDE WITH WHICH ALLAH'S APOSTLE (MAY PEACE BE UPON HIM) HAS BEEN SENT WITH GUIDANCE AND KNOWLEDGE
Abu Musa reported Allah's Apostle (may peace be upon him) as saying: The similitude of that guidance and knowledge with which Allah, the Exalted and Glorious, has sent me is that of rain falling upon the earth. There is a good piece of land which receives the rainfall (eagerly) and as a result of it there is grown in it herbage and grass abundantly. Then there is a land hard and barren which retains water and the people derive benefit from it and they drink it and make the animals drink. Then there is another land which is barren. Neither water is retained in it, nor is the grass grown in it. And that is the similitude of the first one who develops the understanding of the religion of Allah and it becomes a source of benefit to him with which Allah sent me. (The second one is that) who acquires the knowledge of religion and imparts it to others. (Then the other type is) one who does not pay attention to (the revealed knowledge) and thus does not accept guidance of Allah with which I have been sent. (Muslim, Book 030, Number 5668)
Muhammad (s.a.a.w.) was of a height a little above the average. He was of sturdy build with long muscular limbs and tapering fingers. The hair of his head was long and thick with some waves in them. His forehead was large and prominent, his eyelashes were long and thick, his nose was sloping, his mouth was somewhat large and his teeth were well set. His cheeks were spare and he had a pleasant smile. His eyes were large and black with a touch of brown. His beard was thick and at the time of his death, he had seventeen grey hairs in it. He had a thin line of fine hair over his neck and chest. He was fair of complexion and altogether was so handsome that Abu Bakr composed this couplet about him:
"As there is no darkness in the moonlit night so is Mustafa, the well-wisher, bright."
His gait was firm and he walked so fast that others found it difficult to keep pace with him. His face was genial but at times, when he was deep in thought, there there were long periods of silence, yet he always kept himself busy with something. He did not speak unnecessarily and what he said was always to the point and without any padding. At times he would make his meaning clear by slowly repeating what he had said. His laugh was mostly a smile. He kept his feelings under firm control - when annoyed, he would turn aside or keep silent, when pleased he would lower his eyes [Tirmidhi].
His dress generally consisted of a shirt, tamad (trousers), a sheet thrown round the shoulders and a turban. On rare occasions, he would put on costly robes presented to him by foreign emissaries in the later part of his life. [Ahmed, Musnad, Hafiz Bin Qayyim]
His blanket had several patches. [Tirmidhi] He had very few spare clothes, but he kept them spotlessly clean. [Bukhari] He wanted others also to put on simple but clean clothes. Once he saw a person putting on dirty clothes and remarked,
"Why can't this man wash them." [Abu Dawood]
On another occasion he enquired of a person in dirty clothes whether he had any income. Upon getting a reply in the affirmative, he observed,
"When Allah has blessed you with His bounty, your appearance should reflect it." [Abu Dawood]
He used to observe:
"Cleanliness is piety."
